SPECIFICATION forming part of Letters Patent No. 627,637, dated June27', 1899.

Application filed March 6, 1899. Serial No. 707,947. (No model.) i

ets through which the standards of the cultivator-teeth are verticallyslidable and adjustable without being capable of turning from side toside. The faces of the boxes are inclined with reference to the socketsin which the standards move, so that when they are fixed to the inclinedbeams of the frame the standards and cultivator-teeth will always re-.

main in linevparallel with the li-ne of-iravel of the cultivator.

It also consists in an improved mechanism for raising and lowering thefront of the frame with reference to the caster-wheel upon which it issupported. l

Referring to the accompanying drawings, Figure l is a longitudinalelevation of my cultivator. Fig. 2 is a plan of the same. Fig. 3 i's anelevation of one of the boxes. Fig. 4 is a plan. Fig. 5 is a transversesection of the yoke. y

In the class of cultivators to which my invention is applicable theframe is made of a V shape, the side timbers diverging from aV In orderto atpoint outwardly, as shown. tach the cultivator-teeth to theseinclined frame-timbers, it is necessary to provide some means by whichthe teeth can all be accurately held with their points parallel withtheline of travel of the machine, and this in the usual construction of themachine is difficult to effect.

In my invention the divergent frame-timbers A present a certain angle tothe direct line of travel of'the cultivator. Upon the sides of thesetimbers, at points where it is desir'ed to aii'ix cultivator-teeth, aresecured boxes B, having vertical openings C made through them. Theseopenings are in the moving the lever up or down.

present case made rectangular, and the stand ards of thecultivator-teeth are of similar shape and are slidable up andv down inthese openings, so that'they can be adjusted to raise the frame as highabove the teeth as may be desired. When adjusted to suit, the standardsare secured in place by means of setscrews turnable in the outer facesof the boxes, so as to lock the standards at the proper point. In orderto hold the standards and the cultivator-teeth in theexact line oftravel and prevent any of them from being turned out of the line, theboxes B are each formed with al beveled or inclined face, which litsagainst the outer sides of the timbers A, and through the anges of theseboxes bolts pass to secure them in place. At the upper and lower edge ofthe inclined faces -langes b are formed and adapted to engage the upperand lower portions of the side timbers to assist in holding the boxes inplace and to permit of thelready sliding adjustment. The bevel of theinner faces of the boxes has the same inclination with relation to theline of travel as the sides of the frame-timbers. Consequently when theboxes are secured to the frame-timbers the openings C, in which thestandards of the cultivator-teeth are secured, all have the samerelative position to the sides of the framethat is, they stand exactlyin the line of travel and cannot be twisted to one side or the other.The front end of this class of cultivators is usually carried upon aswivel-wheel, as shown at D, having a shank E, which is slidable in avertically-disposed j ournal-box and which has connected with it afulcrumed lever, the long arm of which extends'to the rear of themachine, so that the operator can raise or lower the front of thecultivator-frame by construction the wheel-*shank is located at theextreme front of the cultivator and the fulcrum of the lever betweenvthe wheel and the rear end. This makes it necessary for the operator tolift upon the lever whenever it is desired to raise the cultivator outof the ground. In my invention I reverse the` position of these parts,placing the fulcrum-bar F of the lever G at the extreme front of thecultivator, and the guide or box in which the shank E of the wheel Dmoves is situ'ated'at In the usual IOO a suitable distance in the rearofthe fulcrumbar. The lever G extends back to a point within reach of thedriver at the rear of the machine and is held at any desired point ofadjustment by means of a curved rack H and suitable latching device. Thehead of the wheel-shaft E is swiveled in the lower part of a yoke I,having a nut e upon the upper end to keep it in place, but turningloosely in the lower horizontal portion of the yoke, so that the shaftmay turn freely around its vertical axis to conform to the movements ofthe wheel D.I The lever G passes between the sides of the yoke I and isconnected therewith by a bolt J, which passes through the sides of theyoke and through the lever, as shown, thus allowing a free movement ofthe level' vertically about its fulcrum-bar F and maintaining the shankE of the wheel D in its vertical position slidable through theguiding-socket in the frame of the cultivator. By this construction itis only necessary to apply the weight of the operator to the rear end ofthe lever to raise the front of the cultivatorframe instead of beingobliged to lift the front of the frame, as when the position of thewheel and fulcrum are reversed, as previously described.

The fulcrum-bar F has holes made at intei-vals in its length, so thatthe end of the lever G can be raised 01 depressed to suit the desiredposition of the cultivator-frame.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination in a cultivator of the divergent frame-timbers, teethhaving vertical Shanks or standards, boxes having one side beveled orinclined to correspond with and directly fit the inclination ot' theframetimbcrs to which this side is secured and guide-openings for thestandards, said guides standing at an angle with the inclined faces ofthe boxes and in line with the direction of travel of the machine.

2. In a cultivator, a frame having divergent side timbers, boxes fixedto the sides of said timbers having vertical rectangular openings madethrough them to receive the correspondingly-shaped shanks orstandards ofthe cultivator-teeth, said boxes having one side inclined to an anglewith the standard-openings, said angle corresponding with theinclination of the sides of the frame whereby the standards of the teethare maintained alike in the line of travel of the cultivator, iangesbounding the upper and lower edges of the inclined faces of the boxesand setscrews whereby the standards are adj ustably secured in theboxes.

3. In a cultivator of the character described, a swivel-wheel having avertical standard, a vertically perforated guide boxl through which thestandard is slidable at a point behind the front of the frame, afulcrum-bar pivoted to the frame in front of the swivelwheel havingholes made through it Ifor the adjustment of the lever, a lever pivotedto the fulcrn m-bar extending rearwardly above the shank of theswivel-wheel, a yoke between the sides of which the fulcrum-bar passeswith a horizontal bolt passing through the yoke and the lever-arm, ahead formed upon the top of the swivel-wheel shank and turnable in thetransverse lower part of the yoke whereby the front of the frame may beraised by a corresponding depression of the rear end of the lever and aholding-rack for the lever, substantially as described.
